Description

Technical Field

[0001] This utility model relates to the field of nail gun technology, and in particular to a double-base propellant nail gun structure. Background Technology

[0002] Nail gun cartridges utilize gunpowder energy to achieve rapid fastening. Specifically, the cartridge uses internal gunpowder as a power source, and a spring mechanism on the nail fastener drives the firing pin to penetrate the ignition powder inside the nail. Intense friction ignites the propellant, which in turn ignites the propellant. The resulting high-pressure gas propels the nail out at high speed, thus firmly embedding the nail into the substrate (such as concrete, steel, etc.).

[0003] In existing technologies, when constructing on smooth or high-hardness substrates (such as concrete or steel plates), the nail gun rod is prone to tilting, slipping, or shifting due to the lack of an initial guiding structure, which can lead to anchoring failure or substrate cracking. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a double-base propellant nail structure.

[0005] To achieve this objective, the present invention adopts the following technical solution: a double-base propellant nail structure, comprising a nail rod and a cartridge case holder, wherein a nail base is fixedly connected to the top of the nail rod, a threaded hole is provided on the top of the nail base, a threaded post is connected to the bottom of the cartridge case holder, and the threaded post matches the threaded hole, a propellant loading assembly is provided inside the cartridge case holder, and an auxiliary positioning assembly is sleeved on the bottom periphery of the nail rod.

[0006] Preferably, the propellant loading assembly includes a plastic tube housing fitted inside the cartridge case housing, the plastic tube housing containing ignition powder and propellant, and the outer wall of the plastic tube housing being sealed to the inner wall of the cartridge case housing by adhesive dispensing.

[0007] Preferably, an excitation groove is provided at the center of the top of the plastic tube shell.

[0008] Preferably, the auxiliary positioning component includes a positioning cover sleeved on the bottom periphery of the nail gun rod, and multiple reinforcing nails are uniformly fixedly installed inside the positioning cover.

[0009] Preferably, the bottom of the positioning cover is provided with an annular support portion, and the annular support portion and the positioning cover are integrally formed.

[0010] Preferably, the bottom of the annular support portion is at the same horizontal plane as the tip of the reinforcing nail and the bottom end of the nail rod.

[0011] The beneficial effects of this invention are as follows: After the ignition of the propellant and the propellant, the nail gun rod moves downward at high speed. At the moment the nail gun rod begins to move, the auxiliary positioning component fitted at the bottom of the nail gun rod acts simultaneously. The annular support part closely adheres to the surface of the target object to provide a support reference. The reinforcing nail embeds into the surface of the target object the moment the high-pressure gas pushes the nail gun rod, providing strong anti-rotation and anti-lateral force to ensure that the nail gun rod moves in the predetermined vertical direction. The nail tip of the nail gun rod also penetrates the target object at the same time. Under the continuous push of the high-pressure gas and the stable guidance of the positioning component, the nail gun rod overcomes the resistance of the target object with extremely high kinetic energy, completely penetrates and anchors in it. Through these settings, this device can not only prevent the nail from tilting, slipping or deviating when working on smooth or hard surfaces, significantly improving the vertical accuracy and anti-deflection ability of the nail, but also greatly enhance the single-shot success rate and anchoring reliability through the pre-embedding of the reinforcing nail and the synergistic stability of the annular support part.

[0020] Example 1

[0021] like Figure 1-3 As shown, the present invention proposes a dual-base propellant nail structure, including a nail rod 1 and a cartridge case holder 3. The top of the nail rod 1 is fixedly connected to a nail base 2, and the top of the nail base 2 is provided with a threaded hole 21. The bottom of the cartridge case holder 3 is connected to a threaded post 31, and the threaded post 31 matches the threaded hole 21. The cartridge case holder 3 is provided with a propellant loading assembly 4 inside, and an auxiliary positioning assembly 5 is sleeved on the bottom periphery of the nail rod 1.

[0022] In this embodiment: the propellant assembly 4 includes a plastic tube shell 41 fitted inside the cartridge case holder 3. The plastic tube shell 41 contains an ignition powder 42 and a propellant 43. The outer wall of the plastic tube shell 41 is sealed to the inner wall of the cartridge case holder 3 by adhesive. This setting effectively prevents the propellant 43 from becoming damp and failing, and ensures that the gas pushes the nail gun rod 1 downward along a predetermined path when ignited, avoiding energy loss and safety hazards caused by gas leakage. An ignition groove 44 is provided at the top center of the plastic tube shell 41. This setting facilitates the concentration of energy from the nail gun firing pin onto the ignition powder 42, improving ignition reliability and consistency, and ensuring that the propellant 43 is stably ignited.

[0023] Example 2

[0024] like Figure 1-3 As shown, the present invention proposes a dual-base propellant nail structure. Compared with Embodiment 1, this embodiment further includes an auxiliary positioning component 5, which includes a positioning cover 51 sleeved around the bottom of the nail rod 1. Multiple reinforcing nails 52 are uniformly fixedly installed inside the positioning cover 51. This arrangement ensures that, in the initial stage when the nail rod 1 penetrates the target object (such as concrete or steel plate), the reinforcing nails 52 effectively embed into the object's surface to provide anti-rotation torque, preventing the nail rod 1 from deflecting or twisting under impact force, and ensuring accurate and perpendicular injection direction. A ring-shaped support 53 is provided at the bottom of the positioning cover 51. The ring-shaped support 53 and the positioning cover 51... 1 is integrally molded. This integrated structure enhances the overall strength and rigidity of the component. The annular support 53 is in close contact with the surface of the target object before firing, providing a stable support platform, dispersing some of the recoil force, and helping the positioning cover 51 to remain vertical. The bottom of the annular support 53 is on the same horizontal plane as the reinforcing nail 52 and the bottom tip of the nail rod 1. This arrangement ensures that the tip of the nail rod 1, the reinforcing nail 52, and the annular support 53 can simultaneously contact the surface of the target object, allowing the positioning component 5 to work together as a whole to achieve accurate initial positioning and stable support, minimizing shaking or tilting during the nail firing process.

[0025] Working principle: The firing pin of the nail gun strikes the corresponding activation groove 44 area. The impact energy passes through the plastic tube shell 41 to activate the ignition powder 42. The ignition powder 42 burns rapidly, generating a high-temperature flame and gas, which reliably ignites the propellant 43 below it. After being ignited, the propellant 43 burns violently, rapidly generating a large amount of high-temperature, high-pressure gas within the sealed plastic tube shell 41. The high-pressure gas expands downwards, acting on the bottom of the nail base 2. The enormous pressure overcomes the friction between the nail rod 1 and the positioning cover 51, as well as the resistance of the target object, propelling the nail rod 1 downwards at high speed. At the moment the nail gun 1 begins to move, the auxiliary positioning component 5 fitted at the bottom of the nail gun 1 also acts simultaneously. The annular support part 53 provides a support reference by closely adhering to the surface of the target object. The reinforcing nail 52 is embedded in the surface of the target object the moment the high-pressure gas pushes the nail gun 1, providing strong anti-rotation and anti-lateral force to ensure that the nail gun 1 moves in the predetermined vertical direction. The nail tip of the nail gun 1 itself also penetrates the target object at the same time. Under the continuous push of the high-pressure gas and the stable guidance of the positioning component 5, the nail gun 1 overcomes the resistance of the target object with extremely high kinetic energy, completely penetrates and anchors in it.

[0026] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
